1000 HP YorkShipley Boiler

1000 HP YorkShipley Boiler

1000 HP YorkShipley Boiler

(OP)
Hello, I have been trying to find tech information on our 1000 hp boiler, can't find anything in the manual that came with it except the basic stuff. Couldn't find anything on the internet either, I am trying to find out what the max temp for the morrison tube is and the cfm through the morrison. Also was wondering if anyone would know what the max btu/hr input would be.
It is a three pass firetube boiler with enhanced tubes (looks like rifling),and runs on natural gas. Has a Webster burner with a 100hp/3530 rpm motor on the forced draft fan. Exhaust looks to be about 30" in Dia., with FGR/ 12" I.D. if that has any bearing.
We are investigating using a Sloped Grate Green Burner (USNR) in place of the gas burner, any takes on this?
Any and all input would be grealty appreciated.

Richard

It may be possible to convert it to solid fuel burner, but there are many things you will have to consider. You may be limited by things such as flue gas volume, heat transfer area, pressure drop through the firetubes...

Can you post a picture of your boiler?

RE: 1000 HP YorkShipley Boiler

Look for the Heating surface value either stamped on the shell or labeled on the casing. Multiply that value by 5lbs/hr of steam per sq. ft. of heating surface and that will be the steam generated in lbs/hr. Multiply that value by 970 btu/lbs of saturated steams. Divide that value by .75( which is an approximate heater transfer efficiency in the boiler) and that value will be the heat output from the burner. Divide the heat output by .80 ( which is the efficiency of the burner) and that will be the heat input to the burner and that value can give the amount of cu ft./hr of natural gas or propane or the amount of gallons/hr for #2 or Bunker "c" fuel oil. Of course all these values are approximate depending on the boiler and burner efficiencies but at least you will be in the ball park.

Thanks ... I was able to contact an engineer from Webster and get the information I needed. I do appreciate the help.
chicopee ... I will copy your formulas for future use.

Best Regards

Also remember when you are referring to the 1000Hp, it actually means 1000 boiler Horsepower (abbreviated as BHp) which is equivalent to 33,480 Btu/Hr.
